/**
 * compat-tab.css — wizard "Vehículos compatibles" 1.4.46+
 *
 * COMPLEMENTO de los estilos legacy en `front-deferred.css` (que ya define
 * .ks-compat__cats, .ks-compat__cat, .ks-compat__group, .ks-compat__brand-row,
 * .ks-compat__chevron, .ks-compat__brands grid…). Aquí solo añadimos:
 *   - lead AEO con border-left destacado
 *   - skeleton loader durante AJAX
 *   - estados (loading, error)
 *   - layer L4 chips de años (compactos)
 *
 * El visual de chips/marcas/modelos viene del legacy compartido.
